Here is the Kindle 4 and Touch jailbreak using ixtab's data.tar.gz method. There are three ways of using this package, but you must try them in order if one doesn't work (see the readme for more details). Also new to this jailbreak is that I am now including Java kindlet keys with this and all my future jailbreak releases so developers are create jailbreak-signed kindlets (details on the download page and readme) (thanks to PoP for the merged keystore).

Please note that packages on the Kindle Touch cannot work on the Kindle 4 as is and vice versa! Packages for Kindle 3 can be easily ported to Kindle 4, but not as easy for the Touch.

Please note that the Kindle Touch has changed dramatically from the Kindle 3. This means that no current hacks will work as-is on the touch. Additionally, there are currently no tools to create update packages for the new Kindle format. Of course, anyone can uncomment one line from /usr/sbin/otaup to allow old update format, but I'm going to take the hard road and code a new package tool. While that's happening, you can run any shell script by putting it in "runme.sh" on the USB drive and run the jailbreak (it is safe to run as many times as you want). I've also included a VERY BARE-BONES usbnetwork hack. It's no where near as good as Niluje's usbnetwork hack for the Kindle 3. You cannot ssh over wifi and you need to find your root password with Sir Alex's tool when you ssh through usbnet. Therefore, this jailbreak is target at developers mainly, but it's easy enough for anyone to run.

Special thanks to:
-hondamarlboro, ramirami, ichinomoto for dumping the NAND (couldn't have analyzed the files without it)
-The helpful folks in the IRC (irc://irc.freenode.net:6667/kindledev)
-Amazon (for making it easy this time)
-Anyone who supported me

Thank you yifanlu for all the hard work, and special thanks to the Kindle Touch Jailbreak Support Team for funding your research and giving you the courage (and encouragement) to crack open your Kindle Touch.

Now it's important to follow the naming rules or the screensaver won't show up or worse, the screensaver module will crash and you need to restart the kindle after you fix it.

1) Each image MUST be a grayscale PNG that is 600 × 800
2) Each image MUST be named bg_xsmall_ss##.png, where ## is a two digit number from 00 to 99
3) You MUST have an image named bg_xsmall_ss00.png and you CANNOT skip a number (ex: bg_xsmall_ss00.png, bg_xsmall_ss02.png but no bg_xsmall_ss01.png)

The image displayed is in the order of the number
(You CAN delete, replace, and rename images already in the folder. They are just copies.)
